Our St. Mary school Girl Scout troop needs your help! They are competing in the Greater Lafayette Commerce Window Wonderland this weekend. Twenty downtown Lafayette business storefronts have been decorated for Christmas by student teams. The St. Mary’s troop adopted Pete’s Diner at 601 Main Street. The Greater Lafayette Commerce is doing a contest and the storefront with the most votes gets $1,000. If they win, the girls would like to donate a percentage of the proceeds to a charitable cause. Here is how you can help this weekend.
